The story is set during the mid-to-late 1980s in Punjab, India, a period marked by violent insurgency triggered by Operation Blue Star, the assassination of Prime Minister Indira Gandhi, and the subsequent 1984 Sikh Massacre. The narrative unfolds through a series of intense flashbacks.
Jaswant Singh Randhawa and his sister, Veerendar "Veeran," live peacefully with their elderly mother, Biji, in a rural village. Kripal Singh, Jaswant’s childhood friend and Veeran’s fiancé, lives nearby with his grandfather. Their tranquil existence is shattered when Assistant Commissioner of Police Khurana and Inspector Vohra arrive in search of Jimmy, who is accused of attempting to murder a member of the Indian Parliament, Kedar Nath.
When interrogated, Jaswant plays a prank by leading the police to his puppy, Jimmy. Infuriated by his defiance, Khurana and Vohra take Jaswant into custody. Kripal desperately searches for Jaswant, visiting several police stations but finding no trace of him. After 15 days, Jaswant returns home, severely beaten and scarred from brutal police torture, all for a harmless prank.
Kripal, outraged by the police brutality, seeks help through legal channels but finds no justice. Frustrated, he decides to track down his cousin Jeetay, who is connected to militant groups. Kripal’s search leads him to a highway restaurant (dhabha), where he encounters Sanatan, a militant who had planted a bomb on a bus. Kripal asks for Sanatan's help, and Sanatan reluctantly agrees, allowing Kripal to travel with him, a "Commander," and other militants in a truck loaded with bombs.
Once they arrive at the militant hideout, Kripal explains his situation. The Commander reveals that he killed Jeetay for being a police informant. Despite Kripal’s plea for assistance, the Commander rebukes him, stating that they are not professional killers and that if Kripal wants justice, he must take matters into his own hands by killing Khurana by himself.
Kripal gradually earns the trust and respect of the militant group. Sanatan explains that Kripal's fight is not about nationalism or religion, but about defending fundamental civil rights and resisting a corrupt system that victimizes the innocent and devalues ordinary citizens. It is revealed that Sanatan himself is a survivor of the communal violence during the Partition of India in 1947 and lost most of his family in the 1984 anti-Sikh riots. He asserts that the ruling class manipulates society by dividing it along religious lines for political gain.
